Dolphin researchers have collected an impressive amount of data over the last twenty years, thanks to advances in technology for monitoring, recording, and analyzing dolphin behavior as well as increasing interest in exploring and modeling dolphins' cognitive capacities. Dolphin Communication and Cognition offers a comprehensive reference to the latest research on dolphin communication and cognition, reporting on findings from both the laboratory and the field. The contributors review a wide range of topics, including vocalization, abstract reasoning abilities, imitation and learning, social cognition, echolocation, and ethical issues in working with cetaceans. Dolphin Communication and Cognition begins by examining the dolphin brain and its evolution, the anatomy of its unique sound production and reception systems, and its sensory abilities. It next treats communication, reviewing the complexity of dolphins' vocalization, and then describes research on cognition, from both experimental and developmental perspectives. Finally, Dolphin Communication and Cognition considers the future of dolphin research, including a series of provocative questions that remain unanswered, posed by the volume's expert contributors.
